Barbed Flesh

Dozens of barbed thorns erupt from your skin. Any creature that attacks you with a melee weapon attack suffers 1d6 piercing damage with each hit. A creature that is grappling you automatically suffers this damage at the end of each it remains grappled with you.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage inflicted when the target creature moves increases by 1d6 for each slot level above 1st.
